I was a part of the noburp community on the old site. In the last decade it’s been used to cure that. The body metabolizes it after about 6 months, but having that assistance often helps build the muscle memory and people can usually burp after that. I personally had it done twice and can still do small burps at last, and my daughter (toddler, born very prematurely) had it done at the beginning of the year. Her physical medicine doctor mentioned it as a possibility, and when I told him about the burping thing he basically equated Botox in the medical community with Windex in My Big Fat Greek Wedding
